Filed: 1970-10-08
Abstract: 1336169 Electro-photographic copying apparatus CANON K K 8 Oct 1970 [14 Oct 1969] 47971/70 Heading G2H In an electro-photographic copying apparatus wherein an original O is carried on a reciprocating table 3 past an exposure lamp L, movement of the table is used to control the feeding of electrophotographic copying paper P from a roll and the cutting of a length of paper corresponding for the length of the original. Rightward movement of the table on rails 2 initiates drive to rollers 8 which move the leading end of the paper past a charging station B to exposure station C. Leftward movement of the table permits continuation of the paper feed by rollers 8 until an adjustable stop 31 trips microswitch MSC. Rollers 8 are then disengaged from the drive and cutters A operate to sever a length of paper from the roll. Simultaneously with this final feed movement and continuing thereafter rollers 10-14 move the paper through exposure station C (where it is imaged from the original through a slit via mirror 6 and lens 7) a developing station D and drying station E. When an original of a different size is to be copied the stop 31 is adjusted to cause earlier or later operation of the cutters A.

Abstract: 1518126 Digital colour television BATTELLE DEVELOPMENT CORP 24 Nov 1975 [23 Jan 1975] 48261/75 Heading H4F Digital colour television system in which the composite signal transmitted or recorded comprises a luminance component and line alternating chrominance components; the chrominance components in the received or played back composite signal being delayed in a digital delay device and combined with the received or played back composite signal to thereby produce a line signal output including a luminance component and the two different chrominance components at least one of which was obtained from a received or played back composite line signal other than that from which the luminance component was obtained. In a first embodiment (Figs. I and 2, not shown) the composite signal that is recorded e.g. on a magnetic tape or an optical digital record, comprises in odd lines an I bit between each luminance word of four bits and in even lines a Q bit between each luminance word of four bits. After playback the chrominance components I and Q are separated from the luminance components, delayed for one line period and recombined to form a composite signal including I and Q components and luminance components during each line period which are decoded and formed into a standard NTSC signal. In a second embodiment (Figs. 3 and 4, not shown) the composite signal comprises I and Q bit words inserted alternately in the horizontal blanking periods following the end of each line of luminance words, these latter luminance words having been delayed for one line period i.e. the I and Q words are associated with luminance words from the previous line. After playback the I and Q words are fed to two respective recirculating storage shift registers which each have two outputs, one having a short time delay of less than one line period and the other a long time delay slightly greater than one line period. The resulting composite signal comprises Y words and I or Q words from a first previous line and Q or I words from a second previous line.

Title: Automatic tuning circuit
IPC: H03J7/26
Filed: 1972-10-20
Abstract: 1347436 Automatic receiver tuning; FET ramp generator SABA SCHWARZWAELDER APPARATE-BAU-ANSTALT AUGUST SCHWER SOEHNE GmbH 20 Oct 1972 [3 Dec 1971] 48365/72 Headings H3Q and H3T In a circuit for automatically tuning a receiver, a tuning voltage UT is obtained by charging and discharging a capacitor 26 which is connected to a FET 2, and is connected during the tuning operation via a contact of a relay 4, controlled by a first bi-stable flip flop 9 actuated in dependence on the switching state of a second bi-stable flip flop 8, either to earth or to a charging voltage and the first bi-stable circuit 9 operates the relay 4 from an impulse generated in response to a signal obtained after frequency conversion of the received signal by means of an oscillator 13, a mixer 14, a rectifier 16, and a Schmitt trigger 17 so that the relay is released by the first bi-stable 9 to disconnect the capacitor from earth or the charging voltage. Pressing button 10 causes bi-stables 8 and 9 to turn transistors 6 and 12 on which closes the relay contact 4 so that the capacitor 26 charges via the transistor 6. FET 2 operates as a Miller integrator to produce a linearly falling tuning voltage at the output UT which causes downward frequency tuning, the FET progressively approaching saturation. A received signal is fed via mixer oscillator stage 13, 14, a narrow band crystal filter 15, a rectifier 16 and a Schmitt trigger 17 to operate the bi-stable 9 so as to release the relay contact 4 so that the tuning is stopped at the charge retained on the capacitor 26. Similarly for tuning to higher frequencies button 11 is pressed which again operates bi-stables 8 and 9 to turn the transistor 6 off and the transistor 12 on. This closes relay contact 4 and the capacitor 26 discharges via resistor 7 to produce an increasing tuning voltage at UT. Again on receiving a signal the tuning is arrested by release of the relay contact 4 which stops the discharge of the capacitor 26. Contacts 10<SP>1</SP>, 11<SP>1</SP> may be provided which open to inhibit the stop signal for a predetermined time during operation of the tuning buttons 10, 11. The switching operations affected by the contacts 10, 11, 10<SP>1</SP> and 11<SP>1</SP> may also be effected electronically. A variable capacity diode is preferably used for tuning.

Title: Continuous motion cinematograph film system
IPC: G03B21/44
Filed: 1976-11-19
Abstract: A film (311) runs continuously in front of a window (312) behind which is placed a prism (314) directing a light beam through the film. After having passed through the film, the light is reflected by an oscillating mirror (315) onto an objective (316) and then it is reflected by a fixed mirror (318) onto a projection screen (317). The oscillation of the oscillating mirror (315) is synchronised with the running of the images so as to compensate for their movement. This oscillation is actuated by means of a spiral cam (321) acting on a lever (320) rigidly attached to the oscillating mirror. In order to reduce the dimensions of the oscillating mirror, and consequently its inertia which is liable to make the image blurred, the length of film scanned by the mirror at each cycle is limited to a maximum of 5 mm by virtue of using a film, the image spacing pitch of which does not exceed this length. <IMAGE>

Title: Improvements in and relating to mass flowmeters
Inventor: RILETT JOHN WALTER
IPC: G01F1/82
Filed: 1963-12-10
Abstract: 1,069,466. Electric selective signalling. ELLIOTT BROS. (LONDON) Ltd. Dec. 7, 1964 [Dec. 10, 1963], No. 48688/63. Heading G4H. [Also in Divisions F1 and G1] A mass flowmeter comprises two rotors coaxial with a conduit through which fluid flows, mechanically linked by a spring. One rotor is coupled to a turbine driven by the fluid, and the phase displacement between the rotors, measured electrically, is proportional to the mass flow rate of fluid through the conduit. As shown (Fig. 1), a turbine 12 is coaxially mounted downstream inside a conduit 1 to drive a shaft 10 and a drum 11 at a speed dependent on the volumetric rate of flow, and a coaxial bladed impeller 9 is linked to the drum by a spiral spring 13. The drum 11 carries a magnet 17 producing pulses in an external coil 19; the impeller 9 carries a magnet 18 producing pulses in a second coil 20. The two pulse trains are processed in an electrical circuit (Fig. 3, not shown), which converts the phase difference firstly into a pulse train whose pulse duration is proportional to the phase difference, and secondly into a proportional voltage indicative of the mass rate of flow of fluid through the conduit. The pulse train with variable pulse duration may be integrated by a counter to give the total fluid flow through the conduit. Radial vanes 5 at the inlet remove any initial angular velocity in the flowing fluid but a controlled amount of swirl may be added by rudders 6 via adjustment gear 7, 8 to calibrate the instrument. The blades 15 driving the turbine 12 may be pivoted but spring-constrained so that their pitch is automatically varied by the flowing fluid to produce a desired speed/fluid flow relationship.
